Answer:
answer 1 and 2 i can answer the others
answer 1 : Lewis Rose, (1785? – 1850/1851?) was according to Texas legend the only man who chose to leave the besieged Alamo in 1836, rather than fight and pass there.
Answer 2 : About 100 Texians were then garrisoned at the Alamo. The Texian force grew slightly with the arrival of reinforcements led by eventual Alamo co-commanders James Bowie and William B. Travis. On February 23, approximately 1,500 Mexicans marched into San Antonio de Béxar as the first step in a campaign to retake Texas.
Hope this helps :)
